Digital BW, The Print

Hi,
I have a 1290 waiting to decided what to do with it.I have no experiencie in
B/W printing.  I have order a cartridge set of UT2 from MIS as I read here
is a good option to start. But I wonder which is the differences between UT2
and the piezotones with the new piezoICC. I ask it because I see a great
diference in their price.
PiezoBW-ICC 1280 Starter Cartridge Kits $299.95
MIS UT2 cartridge set $54
Because it seems to print with the epson drive and to advance workflows with
Paul Roark curves are free.

What I mean is if there is any reason to buy piezo over UT2 regarding
quality, easy use, longevity....

Best regards
Aitor
